PROBLEM TO BE SOLVED: To provide an integrated optical component for laser light source, used in laser marking and the like, and also to provide laser module and a laser marking device each having the component incorporated. SOLUTION: Laser line generators 10-1 to 10-4 each have an entrance plane 3, which makes the captured laser beam turn into a condensed beam or a parallel beam, and a wedge-shaped exiting plane 2 which irradiates the incorporated laser beam in a straight form, and front end 1 of the wedge-shaped exiting plane is formed into a chamfered shape and is molded-in with glass or resin.
